I periodically hit a false neutral on my bike, between 3rd and 4th gear. This weekend it caused a bad crash. I know that part of the problem must be me, I probably get a little tired and don't concentrate on making a crisp shift. But, I was also wondering if this is a sign that the clutch needs replacing, or if it's something else. I have an MSR spring loaded shifter, and the lever is slightly higher than my footpeg. I appreciate any suggestions.
